Recognition of experts according to building code law

Test experts for technical installations and facilities must be recognised. This is done by the highest building supervisory authority on request.

On behalf of the client or the other person responsible under building code law, audit experts check and certify the effectiveness and operational safety of technical systems and facilities in need of examination under building regulations in their respective specialist areas.

The test experts are independent within the scope of the audit tasks incumbent on them and are not bound by instructions from the client.

Test experts for technical installations and facilities must be recognised by the competent body.

Decisive for the recognition is the ordinance on recognized experts for the examination of technical systems according to building code law. Thereafter, a person is recognised as an expert or expert upon request up to the age of 70.
